Field of application

Unsurpassed reliability, accuracy and long-term stability in critical processes over all industries. The configurable transmitter not only transfers digital converted signals from RTD and TC sensors, it also transfers resistance and voltage signals using PROFIBUS® PA communication. High measurement point availability by means of sensor monitoring functions. Diagnostics information according to NAMUR NE 107. Optimization of the measurement accuracy by sensor-transmitter matching.

2 input channels and PROFIBUS® PA protocol for the conversion of input signals into digital output signals
The device stands out due to signal reliability, long-term stability, high precision and advanced diagnostics (important in critical processes)
For the highest level of safety, availability and risk reduction
Installation in flat-face terminal head as per DIN EN 50446
Optional installation in field housings even for use in Ex d areas - with mounting brackets for wall or pipe mounting

Benefits

Easy and standardized communication via PROFIBUS® PA Profile 3.02
Meets the EMC requirements as per NAMUR NE 21 and the recommendations of NE 89 with regard to temperature transmitters with digital signal processing
Straightforward design of measuring points in Ex-areas through FISCO/FNICO conformity in accordance with IEC 600079-27
Safe operation in hazardous areas thanks to international approvals such as FM IS, NI, CSA IS, NI as well as ATEX Ex ia, Ex nA (Ex nL)
High accuracy through sensor-transmitter matching
Reliable operation with sensor monitoring and device hardware fault recognition
Rapid no-tools wiring due to optional spring terminal technology
